Yes, I think tendonitis is curable. You can go and get a shot, or might can give you a prescription for the pain. Probably after a shot and the medicastion it will get to feeling much better.
yes tendonitis is certainly curable provided you follow up your doctor's instruction carefully if you have it over a year then you must be straining your wrist without any support to it please wrap wrist support bandage and you can also go in for physiotheraphy in which you will be given treatment with wax or electrode
I have researched tendonitis on the web. The condition may be treated before it turns into scar tissue. I would suggest seeking some kind of physical therapy.
